5 Installation The controller must be mounted on the platform inside the airframe by using one of the provided double-sided tapes. When mounting, try your best to mount the controller as close to the C.G. as possible. Pay attention that the edges of the controller unit are all parallel with the corresponding axes of the plane, and make it parallel to the mounting platform. The controller can be attached flat or upright, and even upside down under the plane. The illustration shows you the 4 different mounting orientations. However, no matter which orientation to select, you have to ensure that the side of DATA interface is always pointing to the plane s heading direction, otherwise the stabilizer will not work properly. Flat Horizontal Face Up Flat Inverted Horizontal Face Down Upright Vertical Upright Inverted Vertical Upside Down VERY IMPORTANT! 1. You need only one piece of the double-sided tapes each time. A soft or thick mounting may probably hinder the performance of the gyroscope. 2. Never use the hot-melt glue or nylon ties to fix the controller onto the airframe! 3. The controller is a sensing device, please make enough space around it and keep as far away from other devices or wires as possible. support@hobbyeagle.com 5

6 Connection A3 Super supports a standard receiver or a Futaba s S.Bus receiver. You don t need to connect all of the 7 input channels, just connect those you want to use. The controller will detect the input signal for each channel and enable or disable the correlation functions automatically. For example, if the input [AIL2] is connected, the dual aileron control system will be activated by the controller. It s recommended that you should at least connect the channels for [AIL], [ELE], [RUD] and [MOD]. Standard Receiver Futaba S.Bus / S.Bus 2 When using a Futaba s S.Bus receiver, you can make a single-line connection between the receiver and the controller. Just plug the male to male lead into the input [S.Bus/MOD] and from the receiver s s.bus output pin. In this case, you don t need to connect other inputs of the controller anymore. As the S.Bus is a single-line solution all channels are transmitted via one single line, in order to make the controller distinguish the input signals for each channel correctly, you have to tell it the channel mapping on your transmitter by using the program card or the config software. A3 Super supports a maximum of 16 channels when using S.Bus solution. support@hobbyeagle.com 6

7 VERY IMPORTANT! 1. Please respect the polarities for the plugs going to the controller. The orange signal line must always be on the top and the brown on the bottom. 2. Check all the connectors and make sure that all of them are firmly connected to the pins. 3. If both [AIL] and [AIL2] are connected, the dual aileron control function will be activated. The [OUT1] and [OUT4] are used to connect the 2 aileron servos. If the input [AIL2] is not connected, the controller will switch to single aileron input mode. In this case, you can still plug the 2 aileron servos into [OUT1] and [OUT4], just as using a Y-cable on the aileron. It s quite the same as when using the dual elevator. 4. Please refer to the manual of your radio to find the right way to assign a 3-position switch for flight mode control, and a knob or slide lever for remote master gain control. 5. You have to reboot the controller after you change the receiver type to make the new setting take effect.

8 Flight Modes A3 Super provides 6 different flight modes. Gyro Off Mode Choose this mode to disable the gyros for all channels. The plane will be completely under the control of the radio. The plane will go back to its previous performance when operating it in this mode. Usually it is only used to test. Normal Mode Normal mode is the most basic application of the gyro. In this mode, the gyro will sense angular velocity on each axis and make a momentary reaction. The normal mode is suitable for all types of fixed-wings, it can effectively improve the stability of your plane specially on a windy day. 3D AVCS Mode The AVCS mode is an advanced application of the gyro. By adding an integral algorithm to the gyros, the controller will try to lock the plane to its previous attitude if there is no command sent from the transmitter in a flight. This mode can effectively help you to accomplish such hard actions as hover and knife edge. But this mode is designed especially for the 3D planes, it s not suitable for the planes those not designed for 3D flight. Auto-balance Mode The auto-balance mode is designed for the new beginners or the FPV applications. When operating in this mode, the controller will command the plane to maintain level flight automatically when you release the sticks. When switch it to this mode from any other modes in an emergency, the plane will recover to the level flight automatically, which we call one-click rescue. Auto-hover Mode The auto-hover mode is another form of the self balance ability of the controller. The only difference is that the correction from the gyro will be applied to both pitch and yaw axes, to keep the plane always vertical. When switch to this mode, the plane will lift its nose and start to hover automatically, which we call one-click hover. User Defined Mode This mode allows you to select different mode for each axis, from normal, 3D or gyro off mode. support@hobbyeagle.com 8

9 Stick Control Modes A3 Super provides 2 different control modes for the sticks, including Manual Mode and Automatic Mode. The default is Manual Mode when you first get it. Manual Mode (MM) When manual mode is chosen, the sticks are used to control the surfaces directly as usual. That is, there is no rotation rate or tilt angle locking and limitation when you move the sticks. All the servos will be completely under the control of the radio. It s more obvious to the users because you can see the servos move following the sticks as you expected. The plane will maintain its original control behavior when operating it in this mode. Auto Mode (RR/AR) When using this mode, the controller will take over the control of all servos. The sticks are used to control the rotation rate (RR) on each axis when flying in normal or 3D mode, or the tilt angle rate (AR) on each axis when flying in auto-balance or auto-hover mode. The max rotation rate and max tilt angle can be set in the program card or the config software. In this mode, the controller will handle the position of the surfaces based on the actual rotation rate or tilt angle of the plane intelligently. This is why the movement of the servo will become different from the manual mode. Flight Mode Manual Mode Stick Control Mode Auto Mode Gyro Off Mode MM MM Normal Mode MM RR 3D AVCS Mode MM RR Auto-balance Mode MM AR Auto-hover Mode MM AR User Defined Mode Depends on the flight mode of each axis MM: RR: AR: Stick controls the servo directly. Stick controls the rotation rate on each axis. Stick controls the tilt angle rate on each axis. * Whatever the setting of control mode is, the stick is always used to control the servo directly when operating in gyro off mode or the gyro of the corresponding axis has been disabled. When the stick control mode is set to Auto Mode, we suggest you always set the gyro gain to at least 50% or larger, a lower gain setting will cause the plane hard to control or even crash! support@hobbyeagle.com 9

10 Wing Type A3 Super supports a standard wing type of the fixed-wing, including 1AIL+1ELE, 1AIL+2ELE, 2AIL+1ELE, 2AIL+2ELE, and a delta-wing or V-tail mixing. Connect the servos following the illustration below. support@hobbyeagle.com 10

11 NEVER use the delta-wing and V-tail mixing functions on your transmitter, all you need is to choose a single 4-channel fixed-wing model type on your radio at any time.

Gyro Direction It s extremely important to make sure that the gyro reacts in the correct direction on all axes before flight, otherwise it could lead to losing control or even crash after takeoff! support@hobbyeagle.com 11

12 Confirm the gyro direction on Aileron Quickly move the right wing downward around the roll axis, the right aileron surface should flap down and the left flap up as shown below. Confirm the gyro direction on Elevator Quickly move the nose of the plane downward around the pitch axis, the elevator surface should flap up as shown below. Confirm the gyro direction on Rudder Quickly move the nose of the plane to the left around the yaw axis, the rudder surface should flap right as shown below. 12

13 Quick Start Follow these steps to complete your first-time installation STEP 1 STEP 2 STEP 3 STEP 4 STEP 5 STEP 6 STEP 7 STEP 8 STEP 9 Before installing, make sure all the surfaces are well connected to the servos by the linkage rods. Install the receiver and bind it to your radio system in advance. Switch on the transmitter and create a new model, select a single 4-channel fixed-wing model type. Assign a 3-position switch for the mode control. Assign a knob or slide lever for remote master gain control if needed. Keep all the sticks in the middle position (except throttle). Now mount the controller on the airframe, connect the required channels between the receiver and the controller. Power on the plane, the LED will turn WHITE for about 2 seconds then start to blink very rapidly, which means the gyro is calibrating, don t move the plane and the sticks during this period. After a successful initialization. Insert the program card and select the correct mounting orientation that you are using. Change the receiver type if you are using a S.Bus connection then reboot the controller to make the new setting take effect. Switch to normal mode or gyro off mode. Adjust the center position for all servos, make your desired dual rate or expo settings if needed. Check the direction of movement of the servos by moving the sticks one by one. If the servo moves in an opposite direction, reverse it on your transmitter. Switch to normal mode, check the gyro direction one by one, reverse it if the gyro reacts in a wrong direction. Insert the program card again, assign the desired flight mode to the 3-position switch. If you need to change any other settings, do it now. The installation is complete. It s ready for your first flight. When system is powered on, you must not move the plane and sticks on the transmitter until the initialization is finished (about 4 seconds). support@hobbyeagle.com 13

19 5 6 Basic Settings Flight Mode By using a 3-position switch, you can change the flight mode in flight, here you can assign your desired flight mode for each position of the switch. If the input [MOD] is not connected, system will always default to the mode that has been assigned to Position-1. User Mode Select different flight mode separately for aileron, elevator and rudder. Response Rate A3 Super uses a high sensitivity and high precision MEMs sensor, you need to try your best to reduce the influence caused by vibration during installation. This option give you another way to filter the noise by software. The default setting is Normal, usually it will be suitable for most planes. However, if you have made effective measures to reduce the vibration, you can try a faster response rate setting to get a better performance. On the contrary, you should use a slower rate when the controller is working in a high vibration situation. Servo Frequency It s used to select the working frequency for the servos. To optimize the performance of the controller, the rule is the higher the better! But please note that analog servos usually tolerate only 50Hz. Digital servos usually allow higher frequencies, but this has to be verified in the manual of your servos. If you don t know what the maximum frequency tolerated by your servos is, please leave this option to its default setting. A higher working frequency can lead to failure of your servos! Travel Limit This function is used to limit the maximum travel range for the servos. The max limit is determined by the maximum possible control travel of the mechanism. The limits can be adjusted from 0 to 100%, the default setting is 100%, corresponding to a pulse width from 1020uS to 2020uS. After setting a limit, the range of movement of the servos will be limited within the safety range. The setting for aileron channel will be applied to OUT1 and OUT4. The setting for elevator channel will be applied to OUT2 and OUT5. The setting for rudder will be applied to OUT3. Gyros Here you can reverse the gyro or turn off the gyro separately for each channel. support@hobbyeagle.com 19

20 Wing Type Select your wing type, see Page 10. Mounting Select the mouting orientation of the controller, see Page 5. Gain This tab is used to setup the gain for each flight mode. The gain is affected by many factors there is no standard answer to that how much it should be. You need to fine-tune to get the best result. The plane will be oscillating in the corresponding direction if the gain is set too high, this is a result of over amplification of the gyros, this rapid back and forth movement can make the plane hard to control. But if the gain is too low, the plane will likely to be hard to control. We suggest you start your first flight with a lower gain setting and then increase them gradually. You can also use the remote master gain channel to get a more convenient way to adjust the gain when in a flight. Gain Rate In order to meet more needs, A3 Super provides 3-level (Small, Medium and Large) gain level for each flight mode. You can choose a larger level when the current gain is still not large enough, even when it has been set to the maximum. However it is recommended to use as small level as possible to improve the precision of gain adjustment. VERY IMPORTANT! 1. A3 Super is aimed at all types of fixed-wing airplanes. Usually the default gain settings are ready to go. However, sometimes you still have to adjust the settings manually according to your plane to get the best flying experience. 2. To get the best performance in auto-hover mode, try to use the maximum gain for auto-hover mode. 3. The Auto-balance or Auto-hover gain will be affected by the Normal Gain. Before adjusting the balance or hover gain, you need to get the appropriate normal gain setting first. Radio All parameters related to the radio system can be setup within this tab. Control Mode Choose the stick control mode, see Page 9. Receiver Type Choose the receiver type, remember to reboot the controller after change the type. support@hobbyeagle.com 20

21 Rotation Rate Choose the max rotation rate of the plane. This setting will only take effect when the stick control mode is set to Auto Mode. Also see Page 9 for more details about stick control mode. Max Tilt Angle Choose the max tilt angle of the plane. The setting will only take effect when the stick control model is set to Auto Mode. Also see Page 9 for more details about stick control mode. Stick Deadband The dead band is the range around the very center of the sticks at where the controller will not react. Some transmitters have the problem that when the sticks are brought back after an input, they are not exactly at the same center position as before which may generate a deviation on the corresponding function, although the sticks seems to be in the middle. This parameter can be adjusted between 0% and 10%, the default setting is 5%. You can set it higher if it is difficult to find the stick center position even the stick centering function has been applied already. The dead band setting is for all channels. S..Bus Channels When you are using a S.Bus connection, you need to tell the controller that which channel is using for aileron, or elevator and so on. The controller should be told with the channel mapping before it can work properly. For example, if you are using channel 5 for the flight mode switch function, you have to select CH5 to the input [MOD]. If you are using channel 6 for the second aileron, you have to select CH6 to the input [AIL2]. Select None to tell the controller that you don t want to use this channel. Stick Centering Stick centering is used to calibrate and re-learn the new center position of the sticks. Usually, in the first flight, you need to make a little trim to make the plane flying properly. Once the trims are set on your transmitter. You need to land the plane and perform a stick centering so the controller can re-learn the new adjustments that were just made. The stick centering is only for channels of aileron, elevator, rudder, aileron2 and elevator2, the mode and gain channels will be ignored when calibrating. And for those channels unconnected, the controller will skip them automatically. Stick centering needs only 1 second, while calibrating, the LED will blink WHITE rapidly. Power-on Automatic Stick Centering A3 Super will perform a stick centering automatically every time it starts, so you can change the trims anytime you need, the new center positions will be re-learned and saved in the next time it starts. Remember to keep all sticks (except throttle) in their middle position before power on the controller, and don t move them during initialization. Perform a centering by toggling the switch If you don t want to reboot the controller, you can perform a quick centering by fast toggling the flight mode switch twice (or more) within 1 second. VERY IMPORTANT! 1. If the servos drift to one side slowly when switching to 3D mode, you have to perform a stick centering. 2. NEVER perform a stick centering when in a flight! It can be dangerous because you may probably lost control of your plane for 1 second! support@hobbyeagle.com 21

22 Level Offset This function is used to offset the absolute angle error caused by installation, and try to establish the appropriate level flight attitude of the plane when flying in auto-balance mode. If your plane drops down or up when switch to auto-balance mode, you will need to perform a level offset. Usually you just need to do it once after installation, the result will be stored inside the controller and takes effect all the time. The following illustrations show you that what happens if an angle deviation exists during installation. How level offsetting works? There are 2 methods to perform the level offset, including Manual Offset and Auto Level Calibration. Auto Level Calibration The auto level calibration is much easier we suggest you use this way in your first-time using the controller. Before calibrating, put the plane on the ground and keep it horizontally, click Level Calibration on the program card or the software to start calibration. While the calibration is being performed, the LED will keep blinking GREEN for about 6 seconds, don t move the plane during this period. If you get a rapid RED flashing after the calibration, that means the deviation is too large (larger than±20deg), in this case, you have to re-install the controller. Manual Level Offset Manual offset allows you make a further adjustment for the angles. The max adjustable value is ±20 on both roll and pitch axes. Please note that there is no direct relation between the real moving direction of the servos and the positive or negative sign of the values, because it depends on which mounting orientation or gyro directions that you are using. For example, if the plane keeps dropping down in self-balance mode, you may need to increase or decrease the parameter for pitch to make the elevator surface a little upper than before, until you get a correct support@hobbyeagle.com 22

23 level flight in pitch direction. For ease of observation, you can turn the balance gain larger temporarily when adjusting the parameters, and restore it after you finish the adjustment. VERY IMPORTANT! 1. Usually you would need to make the nose of the plane slightly upwards while performing the level calibration. 2. If the angle deviations are too large, please re-install the controller! Hover Offset The hover offset is quite similar to the level offset. The only difference is the hover offset is used for auto-hover mode, and the offset takes effect in pitch and yaw axes but not roll and pitch axes. You need to hold the plane vertically instead of making it horizontally while calibrating. Refer to the section of level offset if you don t know how to perform a hover offset. Debug Mode The debug mode allows you to observe the real-time data from the controller, such as the radio input commands of all channels and the attitude data from the IMU. 1 Radio Info Area After connecting to the receiver, you can see the stick movements here of all channels. 2 IMU Info Area Displays all required data from IMU, such as the readings of gyroscope and accelerometer, and the estimated angle results. 2 1 support@hobbyeagle.com 23
